Summary

This PR adds the historical pricing APIs and backfill support needed for transfer-time valuation, while also hardening deploy and indexer behavior.

What Changed

  • add pricing endpoints for:
    • current price
    • price-at
    • pricing-context
  • add swap-event persistence and historical pricing backfill tooling
  • add historical replay support for OHLCV-driven valuation
  • prevent stale OHLCV candles from being marked as locked historical prices
  • prevent CoinGecko historical fallback from using future datapoints
  • add overlap protection to the periodic indexer
  • add adaptive RPC chunking for large log-range queries
  • make token-aggregation deploys deterministic
  • clean up runtime and dev dependency audit debt

Validation

  • npm audit -> 0 vulnerabilities
  • npm test -- --runTestsByPath src/api/routes/tokens.test.ts
  • npm run build

Live Verification

  • pricing-context now returns valid locked historical pricing only when the source is acceptable
  • stale fallback responses now return locked: false
  • token-aggregation service on CT 5000 is active

Notes

This PR is the API/backend half of the explorer pricing rollout and pairs with the UI wiring in explorer-monorepo.
